The sky was already slightly bright, and the spy office came with the final new spy report detected in Kaichuan City, and Han Mengyu's 10,000 elite cavalry silver armor soldiers evacuated Kaichuan City.

Because Han Mengyu is not Wanli's army, his solo action really makes Detianfang guess incomprehensibly, whether it is good or bad to leave, whether there is a conspiracy or not, there is no way to know, and 10,000 troops can't do much, if you really want to cause something, you can only think about it in the long run.

The underground is still under construction, and the tunnel is not very wide, so even if there are many soldiers, the progress of the project cannot be accelerated, and the secrecy measures on the ground are also carried out strictly, the enemy must have espionage activities, Kaichuan's city tower was slightly damaged because of the attack the day before, and when the underground project was carried out in Detian, they were also urgently repairing the city tower, so for the rest of Detian the next day, Kaichuan was actually relieved.

It's another night, the two armies are safe, Kaichuan since Han Mengyu withdrew the news of the army into the Detian army, there is no other movement, and Detian's army seems to have no movement but makes the Kaichuan city guard a little uneasy, Yu Chengzong knows that Detian will not be willing to delay for a long time, so that even a small attack is not launched a day, it is really a little weird, if he expected, the next wave of attacks prepared by Detian should be a fierce battle of life and death.

The fist resting on the public case is getting tighter and tighter, the defense on the first day is not bad, and the regular army that can dispatch the miscellaneous army is like a well-trained regular army, and it is considered that he has some ability, but the army of 200,000 makes the strongest attack, and Detian has always been cunning, and the weapons and equipment are also very advanced, and he, a veteran in his seventies, feels that the defense of Kaichuan City is really tight.

Lin Lu as a reinforcement supervisor, in the court and Yu Chengzong's grade is the same, but Lin Lu this person is acceptable, although he is a militant, but also respect the old and respectful, in Kaichuan City are all under Yu Chengzong, the two are discussing the matter of defending the city, a soldier hurriedly sent a letter, the handwriting on the envelope is strong and powerful, indicating that due to Chengzong's personal enlightenment, the secret level is top secret.

Lin Lu consciously stepped back five feet, Yu Chengzong opened the seal with the beeswax seal intact, quickly browsed it, and when he saw the end, he actually stared at the end and said "Huh".

Lin Lu was very curious, which meant that Chengzong had received the letter, and couldn't help but ask. Yu Chengzong was still thinking about the content of the letter, and after a long time, he loosened his tight eyebrows, and his heart, which had been hanging, also settled down, smiled mysteriously at Lin Lu, raised his index finger, and said: "Put it to death, and then live!" ”

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

The war started at dawn again, and the battlefield of rolling stones, arrows, black oil, and gunsmoke did not seem to have anything special, and the battlefield was like this, and it was normal.

However, the attacking side is not violent, the defender is not tight, and the combat effectiveness of the two sides after a day of rest is far less than that of the first day.

Now the purpose of both sides is important to reduce the strength of the other side, the attacker does not pay attention to the city, most of them use light armor bows to shoot the enemy, and the city tower is constantly rolling, every time a piece is smashed, there will be a strong sense of vibration on the ground, there is also a city tower, when the boulder is just started to be smashed, the soldiers on the city tower are also worried that the city tower will not collapse the boulder thrown by themselves, but this idea is really ridiculous, no matter what, the strong and newly repaired city tower is not likely to collapse because of the vibration of the stone.

Yu Chengzong, who has been in the main building, looked at the Detian army that was constantly offensive, and always felt a little weird, it was the battle situation that was too strange, the Detian army had been avoiding a battlefield, he carefully observed for a while, the avoidance of a battlefield should be a long road, although they avoided it is not obvious, and some people disguised and interspersed with the long road, but that road is mostly empty, and they may not be easy to find their omissions below, but as soon as they stand on the city tower, it is clear at a glance, after his observation, The more he felt that the empty passage was too obvious, and one end of the long passage stretched all the way to the walls of Kaichuan Castle.

Suddenly shocked in his heart, the seventy-year-old old general actually lay directly on the ground of the main city tower and listened carefully. With a pressure on his hand, the soldier who ordered the stone throwing stopped throwing the stone, helplessly, the horse and the car rolled under the city, although Yu Chengzong was old, his ear power was not bad, but he still did not hear the sound he wanted to hear.

Crawling up with a stomach full of doubts, the soldier who threw the stone next to him saw that it was okay, and continued to push a boulder down when Yu Chengzong didn't have time to stop it.......

"Boom!" The moment the rock fell, the sky shook!

"The city has fallen, the city has collapsed ......!"
